Magnetic North (not True North). If the unit detects large installation errors (unit is not well levelled or not aimed to the North), then LCD will show result “444” and “99”, which means that correction was not performed due to incorrect setup.
Compass calibration
If the System was exposed to a strong magnetic field or was not in use for a long time, the compass accuracy may diminish.
To return the compass into working condition:
Select CALc from CAL menu
Keeping the unit horizontal, perform one full rotation around vertical axis within half a minute and then one full rotation around vertical axis with device upside down during half
a minute.
If one rotation does not restore calibration – perform two rotations.
Normal compass function should now be restored.
Gating mode
In this mode gating function is activated. Here the minimal distance to the target can be set. Any object closer than the gating distance will be ignored.
To select Gating Mode:
Select GAtE from the mode menu
